Mass SMS Alerts Now Support Photos, Videos & Audio for Construction Teams

Clear communication is essential on every construction project. Whether teams are responding to severe weather, sharing a safety update, or notifying workers of a site access change, the ability to quickly communicate information can help improve coordination and safety across the jobsite.

That's why we're excited to announce a major enhancement to Kwant's Mass SMS Alerts feature: media attachments are now supported.

Project teams can now send photos, videos, and audio recordings directly through SMS alerts, making it easier to provide workers with the context they need to understand and respond to important site updates.

Even better, because alerts are powered by Kwant's workforce data, teams can quickly target exactly who should receive a message—whether that's the entire project, workers currently onsite, site foremen, a specific contractor, or even workers who were in a particular zone or building the previous day.

Whether you're sharing a photo of a safety hazard, a short video showing an access route change, or a voice-recorded message from a superintendent, Kwant enables richer communication without requiring workers to download an additional mobile app.

What's New?

Mass SMS Alerts now support the following media attachments:

Users can either upload pre-recorded media files or record audio using their computer's microphone or video using their device's camera directly within Kwant before sending an alert.

When recording media in Kwant, the platform automatically optimizes file size to support SMS delivery. If uploading existing videos, users may need to compress or reduce the file size to meet the 1 MB attachment limit.

This enhancement gives project teams a more effective way to share visual context, voice instructions, and site updates without switching between multiple communication tools.

Why Construction Teams Need Better Workforce Communication

Large construction projects often involve hundreds—or even thousands—of workers spread across multiple contractors, trades, and employers.

When urgent situations arise, safety teams frequently rely on a combination of group chats, emails, phone calls, radios, and third-party messaging applications to communicate with the workforce. These disconnected channels can make it difficult to distribute information consistently and efficiently.

Just as challenging is deciding who should receive the message. Many communication tools lack the workforce intelligence needed to target alerts, forcing teams to manually manage contact lists or send broad messages to everyone.

The challenge becomes even greater when visual information is needed alongside a message.

For example:

• A weather alert may require a photo showing current site conditions.
• A safety notification may need an image of a hazard area.
• A site access change may benefit from a short video demonstrating the new route.
• A superintendent may want to send a brief voice update to field personnel.

Without a centralized communication platform, teams often spend valuable time coordinating information across multiple tools and communication channels.

The Solution: Media-Powered Mass SMS Alerts

Kwant's Send Alert feature gives project teams a centralized way to communicate with workers through SMS, without requiring workers to install an additional application.

Because alerts are connected to Kwant's real-time workforce data, selecting recipients is simple. In just a few clicks, teams can target alerts to:

• Every worker on the project
• Workers currently onsite using real-time attendance data
• Individual contractors or subcontractors
• Site foremen or supervisors
• Workers assigned to a specific building or work zone
• Workers who were in a particular location during a previous shift or day

This makes it easy to communicate with the people who actually need the information, reducing unnecessary notifications while improving message relevance.

With media attachment support, teams can include photos, short videos, and audio recordings alongside alert messages, helping workers better understand site conditions and required actions.

By combining workforce intelligence with rich SMS communication, project teams can deliver more complete information than text-only alerts allow.
